Title: High-speed search method for disk player
Inventor: HANYA TOSHIMASA
IPC: G11B21/08
Filed: 1987-09-08
Abstract: PURPOSE:To enable a quick random access by deciding the timing of the switching of a slider from accelerating area to decelerating area by a specified method. CONSTITUTION:A pickup 2 detects information from an information detecting spot which is freely rockably in relation to the slider 3. The slider 3 is driven by a quick-response drive motor 14 and moves back and forth in the radial direction of a disk 1. The slider 3 is driven to quickly cross tracks through an acceleration stage in which it 3 is accelerated up to a high speed and through a deceleration stage during which it 3 is decelerated. The deceleration characteristic at the time of supplying a brake force to the slider motor 14 is preliminarily obtained, also a current speed of the slider 3 as well as an accumulated number of tracks is obtained, and based on the results of these, the timing of the switching from the acceleration phase to the deceleration phase is calculated. As a result, a quick random access can be made able.

IPC: C30B25/02
Filed: 1983-11-29
Abstract: PURPOSE:To grow a desired crystal without using a mask, by irradiating a selected area on a substrate placed in an atmosphere of a compound containing a substance to be grown into the crystal with light at a wavelength for decomposing the above-mentioned compound from the above-mentioned substance. CONSTITUTION:In growing a crystal of GaAs or GaAlAs on a substrate 2, Ga(CH3)3, AsH2 and Al(CH3)3, are diluted with H2, and supplied from injection holes 11,12 and 13 into a vessel 1 to form the atmosphere of the compounds. Light at a wavelength for separating the fundamental composition materials of the crystal from the above-mentioned compounds is projected from a light source 4 on a selected area on the substrate 2 to adjust the area to a temperature necessary for crystal growth. For example, if Zn or S is added to the crystal, a compound containing the element, e.g. Zn(C2H5)2 or H2S, is injected from injection holes 15 and 14, and light at a wavelength for dissociating the Zn or S is projected on the substrate 2 to afford the aimed crystal containing the additive.

Title: Read only memory
Inventor: NATSUI YOSHINOBU
IPC: G11C17/06
Filed: 1985-10-08
Abstract: PURPOSE:To eliminate a glitch and the delay of speed by providing a glitch inhibition circuit which inputs N-numbers of row selection signals in an N XM memory matrix, and outputs a signal, which inhibits the glitch from being outputted outside at the time of switching a signal, to a data output circuit. CONSTITUTION:When an address input signal A0 changes from '0' to '1', a selected fixed memory cell C00 is shifted to C01. At this time a state '1' occurs together with row lines W0 and W1 only for a time (t), and a selected column line D0 rises temporarily. Since AND conditions hold in a NAND gate N for the time (t), the gate is turned on and an output becomes temporarily a low level. When an output level Dout is going to come to '0', the output is conversely made into '1'. Thus, even if the column line D0 rises, the output level Dout never comes to '0', the glitch will not occur at the time of transition from '1' to '1'. Besides, the NAND gate N is installed in parallel with a read current bus, whereby the delay of an access time never occurs.

Title: Printed wiring board insertion error preventive device
Inventor: INASAKA TOMOYOSHI
IPC: H05K7/14
Filed: 1988-09-09
Abstract: PURPOSE:To prevent misinsertion by disabling power current supply in case that a wiring board is mounted in error. CONSTITUTION:Logical cards (printed wiring boards) 1a-1n are connected as specified. In the case that the logical cards are mounted correctly, since signal lines 7a and 7b for discrimination of misinsertion are not connected and a relay 11 is a normal-close contact, when a power source switch 8 is turned on, a normal-open relay 9 closes and power source currents are supplied. If the logical cards 1a-1n are mounted in error, the signal lines 7a and 7b are connected, and the contact of the relay 11 opens, and even if the power source switch 8 is turned on the contact of the normal-open relay maintains the opening, and the power source currents are kept interrupted. According to this constitution, since there is no necessity of providing a specific mechanical selection mechanism in the board the mounting intervals between the boards 1a-1n can be narrowed.

Filed: 1988-09-08
Abstract: PURPOSE:To reduce the sent data quantity and to attain the transmission of a picture with high picture quality in a visual sense by increasing the number of coded bits for a picture element in the middle of each pattern and decreasing the number of coded bits for picture elements at the surrounding part. CONSTITUTION:Since the sensitivity is visually low at the peripheral part in comparison with the middle of the pattern in general, the number of coded bits of each picture element in the middle of each pattern is increased more than the number of coded bits of each picture element at the end of the pattern. That is, for example, a 3-bit code is assigned to each picture element of an area (a) (3rd area), a 4-bit code is assigned to each picture element of an area (b) (2nd area) and a 5-bit code is assigned to each picture element of an area (c) (1st area). Thus, the data compression rate is increased in the peripheral part to send a picture data with high quality visually and the data compression rate is increased.

Abstract: PURPOSE:To obviate the problem of cooling shortage and to surely obtain a cold drink of a low temperature by bringing a hot drink to primary cooling by an instantaneous cooling system, and thereafter, bringing it to secondary cooling by a storage cooling system. CONSTITUTION:Hot coffee used for cold coffee drops down into a pan 35 from an extraction port, and this hot coffee flows down through a spiral hot drink flow-down passage 37. On the other hand, water stored in advance in a cooling water tank 33 is cooled by a cooling coil 34, therefore, the hot coffee flowing down through the hot drink flow-down passage 37 is brought to instantaneous cooling indirectly from both of an outer cylinder 36 side and an inner cylinder 38 side, and brought to primary cooling.
